Please ensure all dependencies are available on the CircuitPython filesystem.This is easily achieved by downloading`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

This will output the documentation to ``docs/_build/html``. Open the index.html in your browser toview them. It will also (due to -W) error out on any warning like Travis will. This is a good way tolocally verify it will pass.
